emptiness

If you take away the petals, stamens, pistil, etc, of the flower, where is the flower itself? “Emptiness” is this concept, that nothing exists of itself on its own side. It is not the same as the concept of an empty glass having no contents, nor is it nihilism. It is part of interdependence, that everything is made of everything else and does not have any independent existence.
